305-044-521-504

Edgeboard Connectors Overview

The EDAC Inc. 305-044-521-504 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 44 positions arranged in a dual row configuration with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector utilizes gold-plated copper alloy contacts with a solder lug termination type. It accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and has a current rating of 5 A.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodates non-specified double-sided PCBs
• Low-profile insulator body constructed from green thermoplastic polyester
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Panel mount installation style with vertical orientation

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connectivity
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation panels
• Automotive electronics assemblies

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and flange characteristics. Ensure compatibility with the target PCB thickness of 0.062 inches (1.57 mm) before integration. Confirm that the vertical panel mount style aligns with the mechanical enclosure requirements. Cross-reference the RoHS status with current regulatory standards for the intended market.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 44 positions is required for vertical panel mounting. The 0.156-inch pitch suits applications needing standard spacing without high-density constraints. Consider the 5 A current rating for power distribution needs within the connector limits. Verify that the low-profile body fits within the available spatial constraints of the assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and termination options to support diverse PCB design requirements. The 305-044 variant specifically provides a mid-range position count suitable for moderate complexity circuit boards.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC ordering guide for direct substitutes within the 305 series. Verify that alternative parts maintain identical 0.156-inch spacing and 44-position counts. Ensure mechanical compatibility regarding panel mount dimensions and vertical orientation.
